107 System for photopyrolitically removing a contaminant US748185 1996-11-12 US5751897A 1998-05-12 David C. Van Alstyne
A system for safely removing even a hazardous contaminant from a substrate surface includes a light energy source whose output is controlled to selectively provide components primarily in the visible and infrared spectrum, and a power unit for energizing the light energy source at a desired energy level, pulse width and pulse repetition rate. Proper selection of these parameters permits the energy source to heat the contaminant sufficiently to cause direct carbonization without entering a melt phase, without the need for any precoat medium. Because the resultant molecular decomposition of the contaminant occurs relatively faster than heat transfer to the underlying substrate, substantially no substrate heating results. The light source energy transforms the contaminant to an ash that is removed from the substrate by a vacuum system preferably surrounding the light source. The light source is preferably a xenon flash lamp operated with a pulse repetition rate of between about 0.1 pulses/second and 12 pulses/second, an energy pulse duration of about 400 .mu.s to about 800 .mu.s, and a peak energy per pulse exceeding about 3,750 joule. The system also provides a mechanism for selectively emphasizing either the visible light or the infrared light spectrum output from the light energy source, to further customize the energy output to the contaminant being removed. A robotic mechanism preferably moves the light energy source over the substrate in applications where a long dwell time is desired to vitrify a contaminant.
108 Method and apparatus for treating waste and for obtaining usable by-product US237372 1994-05-03 US5648592A 1997-07-15 Charles L. Pierce
The present invention is directed to the art of treating waste using laser technology. Industrial and toxic waste materials are irradiated with a laser inside a reactor chamber such that they are heated to high temperatures. Organic compounds are thermally destroyed and chemical bonds are broken. Cool oxygen is pumped into the reactor to provide a refractory protective shield. Silica is added into the vessel at the high temperatures and encapsulates any heavy metals into its crystal matrix. The resulting solidified product may have a hardness of at least 8 on the Knoops scale of hardness and may be used as tooling, road material, oven lining, building materials and the like.
109 Method of treating refractory activated carbon by exposure to ionizing radiation US158816 1993-11-29 US5414204A 1995-05-09 Masakazu Hosono; Hidehiko Arai; Teijiro Miyata
The improved method of treating activated carbon having an organochlorine compound adsorbed thereon which comprises adding water to said activated carbon and then exposing said activated carbon to ionizing radiation, thereby decomposing and rendering harmless the organochlorine compound adsorbed on the activated carbon is described. The method is capable of safe and efficient decomposition of the activated carbon that has been used in adsorption treatment of organochlorine compounds such as PCBs and trichloroethylene that have heretofore been difficult to treat. The activated carbon that has hitherto simply been accumulated to date after adsorbing organochlorine compounds can be effectively treated by the method at low cost.
110 Method of decontaminating a contaminated fluid by using photocatalytic particles US944198 1992-10-09 US5294315A 1994-03-15 Gerald Cooper; Matthew A. Ratcliff
A system for decontaminating the contaminated fluid by using photocatalytic particles. The system includes a reactor tank for holding the contaminated fluid and the photocatalytic particles suspended in the contaminated fluid to form a slurry. Light irradiates the surface of the slurry, thereby activating the photocatalytic properties of the particles. The system also includes stirring blades for continuously agitating the irradiated fluid surface and for maintaining the particles in a suspended state within the fluid. The system also includes a cross flow filter for segregating the fluid (after decomposition) from the semiconductor powder. The cross flow filter is occasionally back flushed to remove any semiconductor powder that might have caked on the filter. The semiconductor powder may be recirculated back to the tank for reuse, or may be stored for future use. A series of such systems may be used to gradually decompose a chemical in the fluid. Preferably, the fluid is pretreated to remove certain metal ions which interfere with the photocatalytic process. Such pretreatment may be accomplished by dispersing semiconductor particles within the fluid, which adsorb ions or photodeposit the metal as the free metal or its insoluble oxide or hydroxide, and then removing the semiconductor particles together with the adsorbed metal ions/oxides/hydroxide/free metal from the fluid. A method of decontaminating a contaminated fluid is also disclosed.
111 Tunable plasma method and apparatus using radio frequency heating and electron beam irradiation US629424 1990-12-18 US5256854A 1993-10-26 Leslie Bromberg; Daniel R. Cohn; William C. Guss; Barton G. Lane; Donna L. Smatlak
A method and apparatus for the pyrolytic destruction or synthesis of gases via a highly tunable combination of radio frequency heating and electron beam irradiation is disclosed. The method is appropriate for destroying toxic gases emanating from hazardous wastes and for synthesizing new molecules from the molecules of a gas. The method is also appropriate for creating scavenger gases and hot gases with large enthalpy for use in sterilization procedures, for example. Embodiments are disclosed employing inductive or direct waveguide/cavity coupling of radio frequency power to the gas. In embodiments of the invention, magnetic fields are used to modify the paths of the electrons in the beam to facilitate tuning and improve the energy efficiency of the system. In a two-stage system, solid and/or liquid wastes are first heated in order to vaporize the toxic materials. Then, the gases produced in the first stage are destroyed by the combination of radio frequency heating and electron beam irradiation of the invention.

114 Photodecontamination of surfaces US96064 1987-09-08 US4867796A 1989-09-19 John Asmus; Keith Boyer
As a method of decontaminating a surface covered with a chemical contaminant, a light-absorption agent providing a relatively high neutral density is applied to the surface in intimate contact with the contaminant. Then one or more flashes of high intensity, broad-band frequency, incoherent light is applied to the surface, whereupon, the light-absorption agent converts the absorbed light energy to heat, resulting in vaporization and/or decomposition of the contaminant. The heat generated by the short duration flash is localized at the material on the surface and at a very thin surface layer, and vaporization of the surface material dissipates the heat that is generated, whereby, the surface is substantially unaffected by the process.
115 Laser photochemical decomposition of compounds containing R--O--P moiety (chemical agents) US588489 1984-03-12 US4529489A 1985-07-16 Joseph K. McDonald; James A. Merritt; Ann E. Stanley
A CW tunable laser is employed in a laser photochemical decomposition met to achieve decomposition of a compound of high toxicity to relatively non-toxic decomposition products.Organophosphorus chemical agents containing a characteristic C--O--P group are irradiated with a predetermined power level from about 10 to about 150 W/cm.sup.2 for a predetermined time period to effect cleavage of the C--O bond. The infrared laser excitation level of radiation in the range of 10.4 .mu.m or 9.4 .mu.m is resonant with the absorption band of the C--O--P group contained in the organophosphorus chemical agent. The absorbed radiation effects cleavage of the C--O bond and thereby achieves decomposition of the organophosphorus chemical agent.The disclosed method is highly selective for cleavage of the C--O bond rather then cleavage of the P--O bond, and in the presence of air, the method requires low power levels of the CO.sub.2 laser for rapid and complete dissociation of the organophosphorus chemical agent.
